Ceiling mounted swing arm lighting apparatus

Abstract

A ceiling mounted lighting apparatus having at least a pair of articulated swing arms connected to a support post by a swivle assembly. Each of the swing arms supports a plurality of lamps each of which may be independently adjustable with respect to the swing arm. The support posts carrying the swing arms are braced to carry the weight of the articulated arms and the lamps affixed thereto.

1. A ceiling mounted lighting apparatus comprising:
 (a) a canopy; 
 (b) means for affixing said canopy to a ceiling fixture; 
 (c) a first support post affixed to and extending from said canopy; 
 (d) a second support post displaced from said first support post, affixed to and extending from said canopy; 
 (e) a first articulated arm pivotally interconnected with said first support post, said first articulated arm including at least two segments pivotally connected together; 
 (f) a second articulated arm pivotally interconnected with said second support post, said second articulated arm including at least two segments pivotally connected together; 
 (g) a plurality of lights carried by each of said first and second articulated arms; and 
 (h) means for bracing said first and second support posts to carry the weight of said first and second articulated arms. 
 
   
   
     2. A ceiling mounted lighting apparatus as defined in  claim 1  wherein said means for bracing includes a first cross brace rigidly connected between said first and second support posts. 
   
   
     3. A ceiling mounted lighting apparatus as defined in  claim 2  wherein said means for bracing includes a second cross brace; and means for coupling said second cross brace to said first and second support posts. 
   
   
     4. A ceiling mounted lighting apparatus as defined in  claim 3  wherein said first cross brace is disposed above said pivoted interconnection between said articulated arms and said support posts. 
   
   
     5. A ceiling mounted lighting apparatus as defined in  claim 3  wherein said second cross brace is disposed below said pivoted interconnection between said articulated arms and said support posts. 
   
   
     6. A ceiling mounted lighting apparatus as defined in  claim 4  wherein said second cross brace is disposed below said pivoted interconnection between said articulated arms and said support posts. 
   
   
     7. A ceiling mounted lighting apparatus as defined in  claim 3  wherein said second cross brace is disposed below said pivoted interconnection between said articulated arms and said support posts wherein said pivoted interconnections for said first and second articulated arms each includes a reduced diameter member extending from said support posts, said reduced diameter member defining a circumferential groove displaced from a distal end of said support post, a tubular member affixed to an end of each said articulated arm, said reduced diameter member being received within said tubular member and a plurality of threaded cylindrical members threadably carried by said tubular member and extending into said circumferential groove. 
   
   
     8. A ceiling mounted lighting apparatus as defined in  claim 3  wherein said second cross brace is disposed below said pivoted interconnection between said articulated arms and said support posts wherein said pivoted interconnections for said first and second articulated arms each includes a first reduced diameter member extending from said support post, said reduced diameter member defining a first circumferential groove displaced from a distal end of said support post, a tubular member affixed to an end of each said articulated arm, said first reduced diameter member being received within said tubular member and a plurality of threaded cylindrical members threadably carried by said tubular member and extending into said circumferential groove; said means for coupling including a second reduced diameter member extending from each end of said second cross brace and defining a second circumferential groove displaced from a distal end thereof, said second reduced diameter member being received within said tubular member and at least some of said cylindrical members extending into said second first circumferential groove. 
   
   
     9. A ceiling mounted lighting apparatus comprising: (a) a canopy adapted for affixing to a ceiling fixture; (b) a first support post affixed to and extending from said canopy; (c) a second support post displaced from said first support post, affixed to and extending from said canopy; (d) a first articulated arm pivotally interconnected with said first support post; (e) a second articulated arm pivotally interconnected with said second support post; (f) a plurality of lights carried by each of said first and second articulated arms; and (g) means for bracing said first and second support posts to carry the weight of said first and second articulated arms, including: a first cross brace rigidly connected between said first and second support posts; a second cross brace; means for coupling said second cross brace to said first and second support posts; said second cross brace being disposed below said pivoted interconnected between said articulated arms and said support posts; and (h) . . . etc. 
   
   
     10. A ceiling mounted lighting apparatus comprising: (a) a adapted for affixing to a ceiling fixture; (b) a first support post affixed to and extending from said canopy; (c) a second support post displaced from said first support post, affixed to and extending from said canopy; (d) a first articulated arm pivotally interconnected with said first support post; (e) a second articulated arm pivotally interconnected with said second support post; (f) a plurality of lights carried by each of said first and second articulated arms; and (g) means for bracing said first and second support posts to carry the weight of said first and second articulated arms, including: a first cross brace rigidly connected between said first and second support posts; a second cross brace; means for coupling said second cross brace to said first and second support posts; said second cross brace being disposed below said pivoted interconnected between said articulated arms and said support posts; and (h) . . . etc.
